Installation Instructions:
Unit should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Remove back plate inside the enclosure by removing four (4) mounting screws (Figs. 2a-7a, pgs. 5-10 ).
2. Mark and drill desired knockouts on the enclosure to facilitate wiring. For suggested wire entry locations
refer to Fig. 1, pg. 4. Use weather tight NEMA 4 rated connectors, bushings, and cables.
3. Unit can be wall or pole mounted.
Wall Mount:
- Mark and drill holes to line up with the top and bottom holes of the enclosure flange.
- Secure enclosure with appropriate fasteners (Fig. 9 and Fig. 9a, pg. 11).
Pole Mount:
- Refer to the detailed pole mount instructions (pg. 11).
Secure enclosure to earth ground.
4. Set power switch on power distribution board marked [PD] to OFF position for models WPTV248UL or
WPTV248ULCB
(Figs. 2b, 3b, pgs. 5, 6). Set power disconnect circuit breaker to OFF position for all
other models (Figs. 4b-7b, pgs. 7-10).
5. All units are factory set for 24VAC operation.
For 28VAC operation adjust unit prior to mounting and applying power as follows:
Change the wire position so that the black wire [28V] is connected to the terminal marked [P] and the
yellow wire [24V] is connected to the terminal marked [S].
Note: WPTV248ULCB set for 28VAC operation is not Class 2, not power-limited.
6. Place back plate with all internal parts, using four (4) screws, back into WP enclosure (Figs. 2a-7a, pgs. 5-10).
7. Connect AC power to the black and white flying leads of the transformer(s) (Figs. 2-7, pgs. 5-10),
secure green lead to earth ground. Use 18 AWG or larger for all power connections.
Keep power-limited (PTC protected outputs only) wiring separate from non power-limited wiring.
Minimum 0.25” spacing must be provided. Use separate entries.
8. Set power switch on power distribution board marked [PD] to ON position for models WPTV248UL or
WPTV248ULCB
(Figs. 2b, 3b, pgs. 5, 6). Set power disconnect circuit breaker to ON position for all
other models (Figs. 4b-7b, pgs. 7-10).
9. Measure output voltage before connecting devices. This helps avoiding potential damage.
Terminals marked [1P - 8P] are of the same polarity.
CAUTION: Determine the maximum operating voltage of the equipment being powered before
adjusting the output voltage.
10. Set power switch on power distribution board marked [PD] to OFF position for models WPTV248UL or
WPTV248ULCB
(Figs. 2b, 3b, pgs. 5, 6). Set power disconnect circuit breaker to OFF position for all
other models (Figs. 4b-7b, pgs. 7-10).
11. Connect devices to terminals marked [1P - 1N] through [8P - 8N] on PD8/PD8CB board
(Figs. 2-7, pgs. 5-10), carefully observing polarity.
12. Set power switch on power distribution board marked [PD] to ON position for models WPTV248UL or
WPTV248ULCB
(Figs. 2b, 3b, pgs. 5, 6). Set power disconnect circuit breaker to ON position for all
other models (Figs. 4b-7b, pgs. 7-10).
13. Green LED will illuminate when power is present.
14. Upon completion of wiring, secure enclosure door with the cam lock (supplied).
Caution: Equipment to be installed/serviced by authorized/trained personnel only.
Shut branch circuit power before installing/servicing equipment.
WARNING: This installation should be made by qualified service personnel. Unit should be installed in
accordance with the National Electrical Codes and all local codes. For continued protection against risk
of fire replace all fuses only with the same type and rating (3.5A/250VAC).
